3.
According to " mechanical-draft cooling tower production engineering specifications " GB/T50392-2006, in most circumstances for counterflow cooling tower, the spray density 12 ~ 14 of big-and-middle-sized cooling tower
; The spray density of small-sized cooling tower is 13 ~ 15
.
By maximum spray density 15
meter, it is 50.015s that water container 1 arrives the minimum time stopping timing water level, if time deviation is 1s, then the relative deviation of surveyed spray density is 2%, and this is also the maximum measured deviation of this method.
For cooling tower, " mechanical-draft cooling tower production engineering specifications " GB/T50392-2006 defines the division of the large, medium and small type boundary of cooling condensation equipment:
Large-scale: single lattice cooling water inflow is more than or equal to 3000
;
Medium-sized: single lattice cooling water inflow is more than or equal to 1000
and be less than 3000
;
Small-sized: single lattice cooling water inflow is less than 1000
.
Consider the size of tower and the force analysis of device in actual measurement process, the connected mode of water container 1 takes two schemes, small-sized cooling condensation equipment, big-and-middle-sized cooling condensation equipment.In explanation below and the application figure is of a size of 2m × 2m for mini-plant, big-and-middle-sized equipment is of a size of 20m × 10m.
As being the small-sized cooling condensation equipment of 2m × 2m for a level cross-sectionn, xsect is divided into nine cells (3 × 3
)(Figure 13), adopt trickle to collect the center of measurement mechanism and each unit of timer measuring to the time needed for certain water-holding quantity, draw trickle flow by volume and time, then divided by the area of water container 1 entrance, obtain spray density, record water temperature simultaneously.After the spray density measuring each cell center, by mean value calculation, draw the spray density of cooling condensation equipment.By device area and spray density, we can draw again the shower water flow of cooling condensation equipment.
In actual mechanical process, in order to obtain experimental data more accurately, xsect can be divided into 4 × 4,5 × 5,6 × 6, even more cell, but require that the area of each cell is identical.
The first step measured goes out cooling condensation equipment cross sectional dimensions with tape measure, then according to the cross-sectional area of cooling condensation equipment, is divided into suitable cell, as 4 × 4 or 5 × 5.Measure the height h on measurement point distance ground simultaneously; Select corresponding measurement mechanism to combine simultaneously.This step can be carried out when cooling condensation equipment downtime, also can carry out when cooling condensation equipment works.
The second step measured is the corresponding measurement mechanism of assembling, according to the parts of first step choosing, according to Fig. 1,2 assemblings, be fixedly connected with scalable connecting link 2 by water container 1, again scalable connecting link 2 is enclosed within two Telescopic supports 3, and liquid level gauge 15 is connected with water temperature display 18 with the water-holding quantity be positioned at outside cooling condensation equipment with the wire 17 of thermal resistance 16, when wire 17 interface is drawn, will inner inlet be avoided.Scalable connecting link 2 is adjusted and Telescopic support 3 makes device maintenance level and balances by level meter 7.
Water container 1 in measurement mechanism is extended measurement point-unit under test center of a lattice, in order to the accuracy measured, before guaranteeing test, keep not intaking in water container 1, then need to keep water container 1 opening to be in shower water falling direction vertical or downward-sloping.
The 3rd step measured utilizes stopwatch to start timing and rotate scalable connecting link 2 simultaneously to make water container 1 opening up, now measured point shower water can drop in water container 1, until by stopping timer during regulation water-holding quantity reading, used time on record timer and be converted to the reading of water-holding quantity by liquid level gauge measured value, and by temperature reading that thermal resistance is changed.By the scale on scalable connecting link 2, device is moved to next cell center to test.Simultaneously can if whole device mobile on Figure 14 to be to other test points, dotted line represents position during other cells of test.Measure successively and record the trickle parameter of each cell center.Measuring process should be carried out when cooling condensation device spray water circulation is stable, and shower water circulation is more steady, and measurement result accuracy is higher.
The 4th step statistics measured also calculates: according to the data of the 3rd step gained, calculate the spray density of each cell, and recycling average draws the spray density of whole tower; The shower water flow of whole tower can be calculated according to cross-sectional area simultaneously; And list provides the distribution of shower water temperature.
As being the big-and-middle-sized cooling condensation equipment group of 20m × 10m for a level cross-sectionn, because big-and-middle-sized equipment cross-sectional area is excessive, therefore adopt as Fig. 6 to Figure 10 map device.
Measuring process and mini-plant similar, specific as follows:
The first step: go out cooling condensation equipment cross sectional dimensions with tape measure, then according to the cross-sectional area of cooling condensation equipment, is divided into suitable cell, as 20 × 10 or 40 × 20, even more multi-cell, but requires that the area of each cell is identical.Next by measuring the position choosing suitable installation hawser fixed head 4.Second step: assemble corresponding measurement mechanism, according to selected parts, assembles according to shown in Fig. 6 and Fig. 7, connects by water container 1 and carriage 9, puts on two hawsers 5 and five stay cords 6; Be placed in outside air-inlet window by hawser fixed head 4, hawser 5 is in straight condition by euphroe 8 and is positioned on the blinds of air-inlet window by hawser fixed head 4; Liquid level gauge 15 is connected with water temperature display 18 with the water-holding quantity be positioned at outside cooling condensation equipment with the wire 17 of thermal resistance 16, when wire 17 interface is drawn, will inner inlet be avoided.Pull the stay cord 6 on carriage 9, carriage 9 is dragged, and water container 1 slides along hawser 5 together, water container 1 is arrived survey the center of cell.The stretching stay cord 6 be under water container 1, makes water container 1 opening down, ensures that it is not intake obliquely.3rd step: utilize stopwatch to start timing, and the stay cord 6 loosened under water container 1 makes water container 1 opening up (because its opening is partial in connection rotating shaft 12 position of water container 1 simultaneously, center of gravity is then partial to bottom, when loosening the stay cord 6 under water container 1, under gravity, the opening meeting auto-steering of water container 1 upward); Now measured point shower water can drop in water container 1, until by stopping timer during regulation water-holding quantity reading, and used time on record timer and be converted to the reading of water-holding quantity by liquid level gauge measured value, and by temperature reading that thermal resistance is changed.By pulling stay cord 6 on carriage 9, device is moved to next cell to test.This stay cord 6 does a mark with 50cm, is convenient to test.Can move whole device as shown in figure 15 to other test points, dotted line represents position during other cells of test simultaneously.Measure successively and record the trickle parameter of each cell center.Measuring process should be carried out when cooling condensation device spray water circulation is stable, and shower water circulation is more steady, and measurement result accuracy is higher.
4th step: statistics also calculates.According to the data of the 3rd step gained, calculate the spray density of each cell, recycling average draws the spray density of whole tower; The shower water flow of whole tower can be calculated according to cross-sectional area simultaneously; And list provides the distribution of shower water temperature.
